MACHINE FOR RAISING FLUTES ON DRAWING AND OTHER ROLLS- Patented June 25, 1907.

Application filed Au ust, 13, 1906. Serial No. 330,420.

To all whom it may concern:

Be it known that I, GEORGE A. BATES, a citizen of the United States, residing at Fall River, in the county of Bristol and State of Massachusetts, have invented new and useful Improvements in Machines for Raising Flutes on Drawing and other Rolls, of which the following is a specification.

This invention relates to machines for raising flutes on drawing and other rolls.

The fluted rolls which are used in drawing machines in the manufacture of cotton become worn after they have been used for some time and have to be re-fluted which'is usually done by planing out the grooves. This operation, however, makes the roll smaller and necessitates changing the draft of the machine each time the roll is refluted.

The object of the present invention is the provision of a simple and inexpensive machine by which drawing and other rolls may be readily re-fluted by pressing out the grooves, and thus pressing up the flutes, without making the drawing roll smaller, so that the roll may be replaced in the drawing machine without having to change the draft of the latter.

The invention is set forth fully hereinafter and its novel features are recited in the claims.

In the accompanying drawings :Fi ure 1 is a side elevation, showing fluted rol s in the machine, ready for re-fluting; Fig. 2, a cross-section on line 22 of Fig. 1; Fig. 3, a cross-section on line 3'3 of Fig. 1; and Fig. 4, a detail of the adjustable connection between the crank wheel and pitman.

The bed 1 of the machine may be a wooden plank, if desired. Standards 2, which are bolted to bed 1, have clamp-boxes 3 at the upper ends in which is firmly held a guide bar 4, which is square in cross-section. Secured to a shaft 5, which is mounted to turn in bearings 6, are arms 7 provided with boxes 8 at their free ends in which a cross-sectionally square supporting bar 9 is rigidly held against endwise movement by endnuts 10. Any desired number of pillow blocks 11 are secured, by means of collars 12 having set screws 13, to the bar 9. These pillow blocks are adjustable to and may be clamped at any desired position alon the length of the bar 9 and their upper en s are adapted to receive the journals of the drawing roll 14 which may have been placed thereon for re-fluting by the machine. A weighted arm 15 secured to shaft 5, tends to swing the arms 7 and drawing roll upwardly.

A frame 16, which is secured to bed 1, has upper and lower arms 17 and 18, the former overhanging the guide bar 4 and the latter projecting under bar 9 and provided with a vertical hand-screw 19. livoted to the frame 16 at 20 at opposite sides or edges thereof so as to swing in a vertical plane, is an abutment plate 21 which is provided with a copper wear facing or plate 22. Secured at 23 to the arm 17 is a yoke made in twin parts 24 and 25 which are notched at 26 and 'are firmly clamped to the guide bar 4- by bolts and nuts 27, by which construction the guide bar 4 is made rigid with the frame 16 and hence with bed 1, as the arm 18 is secured to said bed.

Formed in twin parts 28 and 29 connected together by bolts and nuts 30 is a slide box which is slidable on guide bar 4 between the depending parts of yoke 2425, said box being provided with copper wear plates 31 and 32 held by screws 33 and 34. Journaled in plates 35 and 36 which are fastened to .the sections 28 and 29 of the slide box, is a rotary cutter whose periphery is V-shaped, said cutter being disposed directly over the fluted roll 14.-

At one end of the bed 1 is a shaft 37 carrying a wheel 38 and a belt pulley 39. The wheel 38 is provided with a radial slot 40 whose inner end lies close to the hub of the wheel. A pitman 41, one end of which is attached at 42 to the rear face of section 28 of the slide box, is pivoted to a wrist pin 43 which is adjustably held in slot 40 by nut 44. This construction permits the wrist pin to be so positioned along the slot as to give any desired stroke to the slide box 28'29.

Having placed the drawing roll 14 in position, the hand screw 19 is turned to bring the abutment plate 21 firmly against the roll 14 and cause the latter to bear with any desired pressure against the cutter, the latter being received in one of the grooves of the roll. The machine is then started and the cutter plays back and forth in the groove of the roll, the screw 19 being tightened from time to time, until the flutes have been raised to the desired extent. by pressing up the metal of the roll. The screw 19 is then turned back and the roll 14 turned to bring another groove into line with the cutter, the former operation being then repeated. The roll is The abutment plate 21, frame 16 with arms 7 17 and 18, etc., prevent any springing of the guide bar 4 or the fluted roll and insure accuracy in the re-fluting operation.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is

1. In a machine for making longitudinal flutes on rollers, the combination with a support for the roll to be fluted, of a movable slide box, a rotary cutter carried thereby and j ournaled on an axis transverse to that of the roll, means for moving said sliclebox lengthwise of the roll, and means for pressing the roll against the cutter.

2. In a machine for making longitudinal fluteson rolls, the combination with a movable support for the roll, of a movable slide box, a cutter carried thereby, means for moving said slide box lengthwise of the roll, means co-operating with the support to hold the roll against the cutter, and additional means for exerting pressure on said roll to hold it against the cutter. i

3. In a machine for making longitudinal flutes on rolls, the combination with a movable support for the roll, of a movable slide box, a cutter carried thereby, means for moving said slide-box lengthwise of the roll, and means for holding the roll against the cutter with any desired degree ofpressure, comprising a movable plate, and a screw bearing against said plate.

4;. In a machine of the class described, the combination with a frame having upperand lower arms, of a yoke connected to one of said arms, a slide-box movablewithin the yoke,

means for moving the slide-box, a cutter carried by the slide-box, means for supporting the roll to be refluted, means for pressing the roll against the cutter comprising an abutment plate hinged to the frame aforesaid, and means on the other arm of the frame to press said abutment plate against the roll.

5. In a machine of the class described, the combination with a frame having a yoke, of a slide-box movable within the yoke, a .cutter carried by the slide-box, a movable support for the roll to be refluted, means for moving said support to cause the roll to continuously bear against the cutter, an arm on said frame,

an abutment plate pivoted to the frame, and

a screw passing through the arm and bearing against the abutment plate, said abutment plate being adapted to be brought against the roll with any desired degree of pressure to hold the roll against the cutter.

6. In a machine for making longitudinal flutes on rolls, the combination with pivoted counterbalanced arms carrying pillow blocks forming a support for the shaft of the roll to be fluted, of a slide box movable lengthwise of said roll, a cutter carried by the slide box and adapted to bear on the roll, a drivewheel,

a pitman connected to the slide box, an adjustable connection between the pitman and the Wheel by'which the point of connection can, be moved radially on said wheel, and means for producing a firm pressure up against the under side of the roll opposite to the cutter. i

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
